How To Use The Micrometer For High Quality CNC Parts?

The micrometer also known as the micrometer screw gauge, this device is able to measure small diameters of up to 1.65 mm plus or minus 0.005 mm. It is used in engineering to make sure the measurements are accurate down to the last millimeter. This machine often resembles calipers on opposite sides joined by a frame. The spindle is a very well calibrated screw. When measuring the diameter of an object, it is placed between the spindle and the anvil. There is a thimble engineered to adjust the diameter until the object is between the spindle and anvil. It can be turned to achieve optimum accuracy.

How is a micrometer read?

Having an image of how a micrometer looks like will really help in understanding this. The first step is understanding the two scales available. Two are provided in order to guarantee precision. The first scale is the main scale located on the sleeve, the second one is the rotating Vernier scale on the thimble. There are two parts in the final measurement, for example, 2.65 mm. The first digit is read from the sleeve left of the thimble while the digits after the decimal point are read from the Vernier scale.

What is the proper way to use a micrometer?

There are many tips as to how to properly use a micrometer screw gauge. The following are dos and don’ts that will help:

The micrometer screw gauge has a locking lever installed to inhibit movement when reading measurements. This should always assist when trying to record measurements. Also, always unlock the lever before revolving the thimble. Doing this might ruin the scale.
The surfaces of the spindle and anvil should always be whipped before use. Particles may tamper with the measurements.
Always make sure that you read the scale on the sleeve before the Vernier scale. If the order is mistaken the values will turn out wrong.

How much pressure should be applied during measurement?

In fact, the pressure for testing standard is very important, it need be well controlled, we must exercise the micrometer many times and do it as little as possible. Once you have established a slight grip on the object, the measurement will be accurate enough. At Creatingway, we have trained our quality person and machinist how to use these equipment. So we can ensure parts machined process and final parts can meet requirement.

Why is this important for training skilled machinists?

When building machines, accuracy is a very important skill. Machinists should have mastered this skill before joining the industry. It is important because small mistakes have been known to cause a ripple effect. The effects can be fatal. We should be ruthless in trying to avoid such ends.

Meanwhile, we also need to unify whole our quality system, testing method ( different testing tools for various parts), quality sense and standard, keep quality level in our mind, in order to we can ship high quality CNC parts to our global customers.

How does this help to improve the quality of your parts?

When customers have tested these parts or assembled them. If there is mismatching or dimension is out of tolerance. Customer will be angry and ask recut or refund, this will waste lots of time and cost each other. Maybe reasons is that both quality person or machinist read error this or machined error. In fact, if our quality person and machinist can well use these equipment, if so we can completely avoid default parts to customers, we can improve it inside right now.

Indeed, we can increase our production efficiency and assure the manufacturing of quality parts by ourselves.
